Specification of Letters Patent.

Patented Feb. 24, 1920.

Divided and this application filed June 30,

1919. Serial No. 307,542.

To allavkom it may concern Be it known that I, WI LIAM Lovn THOMP- soN, a citizen of the United States, and a resident of Greenville, in the county of lVashington and State of Mississippi, have invented new and useful Improvements in Printing-lvlachines, of which the following is a specification.

This invention relates to printing machinesand has particular reference to that class of printing machines adapted to be used in printing the names and addresses of consignees upon shipping-tags.

An important object of the invention is to provide in a machine of the above named character a novel means for quickly selecting and setting up the several type characters composing a desired name or address.

A further object of the invention is to pro vide a novel automatic means forbringing a plurality of predetermined selected type selectively into position whereby they may be quickly transferred to their respective positions within the machine.

Another object is to provide a novel automatic means for successively feeding a plurality of tags to the machine and remov ing themtherefrom subsequent to the printing operation.

A further object is to provide a novel automatic means for intermittently supplying a suitable printing fluid to the type or printing characters employed. 7

Another object. is to provide a machine of the character mentioned, having its various cooperating elements so constructed and arranged with respect to each other as to insure accuracy and reliability during the operation of the machine.

Other objectsand advantages of the invention will be apparent during the course of the following description taken in. connection with the'accompanying drawings.

This application is a division of my application filed February 26, 1919. for printing machines, Serial Number 279,315.

In the drawings, forming a part. of this specification and in which like numerals are employed to designate like parts throughout the same. 7

In the drawings, wherein for the purpose of illustration is shown a preferred form of my invention, the numeral 10indicates a base carrying an upright frame member 11 and a supporting member 11- having secured between their upper ends a head 12. I prefer to constructthe base 10 hollow as shown in Fig. 3 in order to receive therein a coil spring 13 from which power to operate the machine as will hereinafter be more fully described is derived;' The spring 13 is secured at one end to the base 10 as shown at 11, its other end being secured to a vertically arranged shaft 15 one end of which is journaled in the base 10 as shown at 16, while its other end is journaled within a bracket 17 carried by the frame member 11. To the upper end of the shaft 15 there is fixedly secured a bevel gear 18 meshing with a second bevel gear 19 carried by a shaft 20. In actual practice I prefer to maintain a ratio of two to one between gears 18 and 19 so that one revolution of the shaft 15 will cause the shaft 20 to rotate through two complete revolutions. The shaft 20 suitably journaled within the frame member 11 as clearly shown in Fig. 3 and carries at its outer end a type wheel indicated as a whole by the numeral 21. In order to render the type wheel 21 as light in weight as possible I prefer to form therein a relatively large circular groove as shown at 22. The type wheel 21 is provided with a plurality of T- shaped type slots 23 adapted to receive loosely therein a plurality of type 24;. For each type slot or row of type I provide a reciprocating plunger 25 one end of which is enlarged ssh wn. 26 11 n rm ly eate within a chamber 27. To the outer end of the plunger 25 is secured a head 28 provided with a character. asv shown at 29,; which.

character corresponds with the characters of the type 24 carried by its adjacenttype slot. To the outer end of the shaft 20 there is detachably secured a crank 30, this crank being adapted to rotate the shaft 15 through the gears 18 and 19 as is apparent,.to wind the spring 13 from which power is derived for operating the various'coiiperating elements as will be hereinafter more fully described.

7 As a means for preventing excessive speed of rotation of the wheel 21 I prefer to emplay a brake mechanism indicated as a whole at 31. This brake mechanism comprises a plunger .32 seated within a slot 33, the plunger 32 being free to reciprocate therein and having its outer end normally engaging the inner face of'the wheel 21.. A slot 34 is providedwithin the plunger 32 and adapt-- edto receive therein a tapered key By forcing the key inwardly it is apparentthat the plunger 32 will be forced downwardly against the face of the wheel. During the operation of the device as the tension of the spring 13 isreleased the tapered pin 35 may be gradually withdrawn topartially relieve the braking effect of the plunger 32 upon the faceot. the wheel 21. In practice it might be found that adifierent form of brake is more-suitably adapted for this purpose than that which I have shown and described herein,.the braking mechanism shown and de scribed herein being intended only as an illustrative showing. By releasing the prescrating with certain other elements to be.

hereinafterdescribed to stop the wheel 21 at predetermined points. -Within the'upright frame member ll-there is pivotally mounted plunger releasing lever37. this lever being pivotally connected with the frame member ll'as shown at 38. Atjsubstantially. right.-

angle to the lever 37 there is disposed a latch stop39 which is pivotally connectedto the ,machine'as a whole as shown at 40. The

latch stop extends substantially to the outer faceof the frame member 11 as clearly shown and'is provided with an upright arm 41 extending ,an appreciable distance. unwardly into a relatively large opening lathe frame member 11. as shown at As a means for retaining the plunger releasing lever 37 and the latch stop, 39 in their nor-' mal respective positions as shown in Fig. 3 there is provided a coil spring 43having one end connected to the latch stop 39 and its other end to the plunger operating lever 37 as clearly shown in Fig. 3.

Between the upright member ll and the supporting member 44 there are ournaled a pair of removable ink ribbons carrying spools 45 and46 "carrying inking ribbon 47' adapted to be intermittently nioved as will be hereinafterdescribed. Upon pins 48 and 49 there are journaled respectively ratchet wheels 50 and 51. The pins 48 and 49 are provided respectively with tapered ends and 53 adapted to enter depressions carried in the ends of the spools, which depressions are arranged centrally within the ends of the spools as is apparent. The ratchet wheels are provided with locking pins and 55 adapted to enter depressions carried by the spools 45 and 4.6 respectively These pins are, as is apparentyadapted to lock the ratchet wheels against rotation with respect tothe rollers or vice versa when the spools are being rotated through the instrumentality of the ratchet wheels 50 and 51. The spools 45 and .46 are provided at their other ends with depressions 55 and 56 respectively which are adapted to receive the ends of plungers 57 and 58, these plungers being urged inwardly by means of coil springs 59 as clearly shown in Fig. 2. It will be noted thateach of the plungers is provided with a head 60 normally seated flush with the face of the depending member 44 within a coun tenbore 61. The heads 60 are inset in order to prevent interference with the feeding ofthe tags during the printing operation as will more fully be appreciated upon further study of the drawings. taken in connection with the specification and described operation of the machine. The'inking ribbon 47 as clearly shown in Fig. 1 passes over apair of guide rollers 62 w'hich'are journaled between the'uprightmember 11 and the sup porting member 544. These rollers are adapted to be removed and are provided at one end withspring pressed plungers 63, these plungers being substantially identical to the plungers 57 and 58 hereinbefore 'described. n

/Vithin the head 12' there is slidably mounted an operating plunger64 provided with a head 65. This plunger is normally retained in the position shown in Fig. 3by means of a coil. spring 66 having itslower end arranged within a chamber 67 and itsupper end engaging a collar 68." To the lower end of the plunger 64 there is connected a stamping head 69, the stamping head carrying upon its upright face a bracket 70 to which is pivotally connected a'pawl 71 adapted to engage theteeth-of the ratchet wheels and 51. In the posi-- tion shown in Fig; l thepawl 711is adapted to engage the teeth of ratchet wheel 51 to" rotate thespool 46 in such a direction as to cause a'windi'ng up of the inking rib- 'bon e7 upon the spool 46, the inking ribbon being at the same time unwound from the spool 45. In the" position of the pawl 71, shown in Fig. 1, the movement of this pawl is limited by a stationary pin 72 and a removablepin 73. By removing the pin 7 and swinging the pawl '71 about its pivotal connection as an'axis to its position shown by the dotted line in Fig. 1, the reverse movement of the ratchet wheels '50 and 5-1 is brought about during the operation of the device, the ribbon 17 being wound upon the spool 45 and at the same time unwound from spool 16. In this position the move ment of the pawl 71 is limited by a stationary pin 72 identical with that shown at 72 and the removable pin 73.

For retaining as a unit certain type necessary in the printing of a consignees name and address I propose to employ type carrying plates such as is indicated by the numeral 745. Each of these plates is provided with slots 75, one of the slots being used to retain the type of a given name, the other being employed to retain the type of a given address. Each of the the plates 74 is further provided with a beveled end as shown at 76 which, as is apparent, functions together with a thumb screw 77 to retain a given plate in printing position within the printing head'69. As a cooperating element for the typecarrying plate71, when placed in printing position within the printing head 69, I employ a detachable bed plate 78 seated within an elongated channel or seat 79, the bed plate being adapted to be inserted into the channel from the leftv of the table 80 which is supported in part by the upright member 11 and a suitable housing 81 carried by the base 10. The bed plate 7 8 is substantially identical with the type carry 'ing' plate 7% in so far as length and thick-- ness is concerned but differs materially in that no type slots are provided therein. It

' often happens that a shipper has one or more customers to whom it is desired to ship material frequent y and in such cases it is found desirable to retain type plates having the type always set up for the printing of the names and addresses of such regular customersjin order to' save time and expedite the matter of addressing tags. In such cases it is only necessary to remove thetype carrying plate 7% from the head 69 and insert another having the desired name and address already set up. hen it 1s desired to set up the type necessary to the names and addresses of consignees to whom shipments am not so frequently made, the bed hen the type necessary to the consignees name has been set up the type carrying plate 74: is moved farther into the channel 79 until the slot adapted to receive the type necessary to the consignees address is brought into registration with the channel 83 through which type from the wheel 21 is moved into the registering slot. I'Vhen the type necessary to the name and address has been set up within thetype carrying plate 74: it is removed from the channel 79 and inserted into the printing head 69 and locked therein by the thumbscrew 77. Before the printing operation is executed, however, the bed plate 78 is inserted into the channel 79 from which thetype carrying plate 7i has been removed.

To the end of the shaft 20 there is securely fixed a bevel gear 8 1 meshing with a bevel gear carried by a shaft 86 suitably journaled within the end of the bracket 17. In actual practice I prefer to maintain a ratio of four to one between gears 84 and 85 so that one quarter of a'revolution of gear 84: will cause a complete rotation of shaft 86. To the lower end of shaft 86 there is connected a disk 87 to which is pivotally connected apitman 88, the pivotal connection being shown at 89. The pitman 88 is adapted to actuate a card feeding mechanism indicated as a whole by the numeral 90. The card feeding mechanism comprises an arcuate-shaped track 91 secured as clearly shown in Fig. 6 to the housing 81. Upon the track 91 there is mounted a movable arcuate-shaped base 92. Between the base 92 and track 91 are interposed bearings 93 which are intended to reduce the friction of the feeding mechanism to a minimum during its operation. The base 92 carries an elongated arm 94- which is pivotally connected to a vertical support '95 secured to the base 10 as clearly shown in Fig. 5. The arm is further provided with a second, arm 96 which is bent downwardly as shown at 97 and again bent horizontally as shown at 98, the horizontally bentportion being pivotally connected as shown at 99 to the pitman 88 To the vertical support 95 and above the arm 94- there is pivotallvconnected asecond arm 100 which is retained in a normal position by means of a leaf spring 101 secured to the arm9a shown at 102. i The arm 100 is provided at its outer end with a flange 103 adapted. to. contact. with down-- wardly depending fingers 104 carried by an arcuate-shaped support 105 which is linked or pivotally connected to the arcuate-shaped to co-act with the arm 100 as will be more tully described hereinafter. Relatively near the other end of the track 91 there is provided a lug" 108 whichis adapted also to (so-act with the arm 100 in a manner hereinafter more fully described. The arcuateshaped support 105 is retained normally in its lowest position with respect to the arouate-shaped base 92 by means of a coil spring 109 having one end connected with the base 92 and itsother end connected with the support 105 as clearly shown in Fig. 5. From the support 105 rises a pair of converging brackets 110 having their upright ends secured to ,a spacing block 111. Upon the spacing block 111 there is secured an arouate-shaped feed bar 112 adapted to traverse an arcuate-shaped slot 113 provided within the, table 80. To eachend of the feed bar there is connected a feed block, the feed blocks being indicated by the numerals 114 and 115 and provided with a plurality of teeth or serrations as shown at 116.

To the supporting member 44 there is suitably connected an upright guide 117, which guide is provided at its lower end with an angularly bentlip 118 arranged in proximity to an opening 119 afforded between the lower end of the member 44 and the upright face of the table 80. The guide bar 117 is further provided with an arcuateshaped portion 120 carrying an arcuateshaped tag retaining member 121 which extends over the inclined portion 81 of the housing 81. The housing 81 relatively near the arcuate-shaped slot 113 is not only inclined as shown at 81' but is depressed circularly as shown at 81". I

To the member 44 there is secured by means'oi a set-screw 122 an elongated U- shaped tag guide rod 123,.the free end of which is'arranged co-axially with the vertical support 95 and beyond the inclined portion 81 of the housing 81 to enable a plurality of cards to beeasily placed upon the rod 123 andto permit thesecards to fall successively one by one from the rod subse- "quent to successive printing'operations. As

a co-acting member for the guide 117 there is provided a second verticalguide, 124 having its lower end angularly bent as shown at 125 and secured to a vertical adjustable bracket 126 carried by the housing 81. In practice I prefer to provide an; elongated slot 127 in-the bracket 126 which makes possible a horizontal adjustment of the guide 124 inorder to vary the space aflorded between brackets 117' and 124 to readily accommodate' tags of various Widths.

' position within the-channel 79 for The operation of the machine is as fol-. lows: Assuming that energy is stored within the spring 13 and a plunger-25 is in engage ment with the latch stop 39 the row of printing type carrying the first desired character is then selected and its adjacent plunger is pushed inwardly softhat its enlarged end 26 enters the groove 36. The plunger releasing lever 37 is then moved against the influence of spring 43 to release the engagement between the latch 39 and the enlarged end26 of the plunger whereupon the wheel 21 is rotated until the plunger adjacent the selected row of printing type comes into contransfer another selected printing type td the selected groove of the type carrying plate 74 the selected plunger 25 is moved inwardly until its enlarged end 26 has entered the groove 36 as above described. The plunger releasing lever 37 is then'moved against the influence of the spring 43 to relieve the engagement between the latch-stop 39 and the previously selected plunger-whereupon the wheel 21 isirotated'by the spring 13 through the instumentality of gears 18 and 19 until the selected printing type are brought into alinement with the groove 83 and the selected groove of the type carrying plate 74 as above described. These successive operations are repeated until the desired name and address or other desired matter is set up within the type carrying plate 74, whereupon the plate is withdrawn from the channel 79 and placed in printing position within the printing head 69. The

bed plate 78 is then placed in its normal printing as hereinbefore set forth.

Having the type all set up and thGVELllOllS elements in their respective positions as described the printing of either ordinary shipping tags and similar cards, or tags such as are indicated by the numeral 130 may be begun. These tags may be the ordinary type, with the usual plain or reinforced eyelets, or they are provided with eyelets asvshown in order that they may be retained upon the U-shaped tag guide rod 123. It is to be understood that since the free end of the U shaped guide .rod 123 is spaced laterally from the table 80 as clearly shown in Fig. 5 that the tags maybe fed on the rod and moved to the dotted line position as shown the influence of the spring 513.

of the brake 31 the speed of rotation of the in Fig. 5. The tags are retained in stacks or columns upon the guide rod 123, each having that portion upon which the name and address is to be printed disposed between guides 117 and 12a. Before beginning to execute the printing operations care must be taken to push four of the plungers 25 inwardly so that their enlarged ends 26 will enter the groove 36. These four plungers must be spaced from each other a distance of ninety degrees as indicated by the arrow opposite. to theposition shown in 5.

The printing head 69 is moved downwardly whereupon the lug 131 is brought into engagement with the arm 41 thereby depress ingv the latch 39 against the: influence of spring 43 releasing theengagement between the enlarged end 2601? the plunger and the latch-stop 39. The hand is removed from the head 65 whereupon the head 69 returns to its normal position under the influence of the spring'66, thereby permitting the latch 39 to return to its normal position under By means wheel21 is sufliciently retarded to permit the latch-stop 39 to assume its-normal position shown in Fig. 3, before the wheel 21 will have; moved, one-fourth of .a revolution. Upon the completion of the o-ne-fourth revolution of the wheel 21 the next successive plunger 25 will have been brought into engagement with the latch-stop 39, thereby stopping the rotation of the wheel 21. By reason-of the fact that a ratio of four to one is maintained between gears 85 and Set the disk 87 will have completed one revolution in which instance the connectionbetween the pitman'88 and the disk 87 will have moved from a point diametrically opposed I to its position shown in Fig. 5 through three hundred and sixty degrees. Before the disk 87 is rotated the feed block 115 is centrally located under the lower tag of a given column oftags, the serrations 116 oflthis feed block being in engagement with the under face'of the lower tag. Since the .pitman 88 is connected to the rotating disk 87 and the arm .96 a'movement of the arc-uate -shaped support 105 is brought about.

completion of, a half revolution'of the dislr. 87 the arcuate-shaped support is moved sub- Upon the sta-ntially tothe position shown in Fig. 5

influence of spring 109 immediately drops to'a lower position until the arms 104: rest upon the upper face of the arcuate-shaped base 92. lVhenfthe downward movement of the arcuate-shaped support 105 is brought about a corresponding dropping of the feed bar 112 is produced. Immediately subsequent to the lowering of support 105 the disk 87 will have completed its one-half turn whereupon the base 92 is moved backward along the track 91, thereby bringing the fingers 10s into engagement with the stops 107 whereupon the support 105 is elevated against the influence of spring 109. lVhen the fingers 10 1 have moved an appreciable distance above the face of the base 92 the arm 100 will be forced under the fingers 10 1 by means of the spring 101, thereby re- 7 taining the feed bar 112 in an elevated posltion. It might be well for me to state here that the spring 101 is not so strong as spring 109, it being only sufficiently strong to move the arm 100 under the fingers 104 when they are lifted from thebase 92, while the spring 109 is of sufiicient strength to retain the fingers 104 firmly in engagement with the arm 100 and the face of the base 92 respectively during the feeding of the tags and the return of thefeed bar 112 to a normal position. Immediately subsequent to the lifting of the feed bar 12 to its upper position thedisk 87 will have completed one revolution. It will be noted from the above that the feed bar 112 is moved in an elevated position about the guide rod 123 as an axis, the guide rod 123 being coaxially ar- I done simultaneously with the release of engagement between the enlarged end 26 of the plunger and the latch-stop 39 and since the printing head 69 returns to its normal position immediately subsequent to printing there is no interferencein .the operation of the feeding mechanism by the printing head. Normallvthe feed block 11 1 is positioned directly below the tag 130. when in a print" ing position. Since this is true the printed tag is moved from under the printing head 69 simultaneously withand .in advance of the movement of the next tag to a printing position. It is therefore apparent that the printed tag is ejected from the machine .si-

I if multa-neously with the movement of a blank tag to printing position. When the printed tag hasbeen moved an appreciable distance from under the printing head its edges are moved clear of the housing 81, thereby perimitting the printed tag to fall or drop the guide rod 123. Immediately subsequent to the ejecting of a printed tag and the placing of ablank tag in a printing position the arm100 is removed from under the fingers 104 as hereinbefore described, thereby permitting the support 105 together'with the feed bar 112 to move to a lower position under the'influence of the springlOQ as hereinbefore described. Y

It might be found desirable in actual practice to employ a suitable clutch mechanism between the shaft 20 and the tag feeding mechanism to render the several cooperating elements thereof inoperative during the type setting-up operation. There are possibly many forms of conventional clutches particularly adapted to accomplish this end and I have therefore not attempted to disclose any given or preferred form. If, however, in practlce it should be deemed undesirable to employ a clutch as above mentioned the feeding of the tags may beprevented during the type setting-up operation by simply lifting the column of tags upon the guide rod 125 and inserting a piece of card board or'the like between the table 80 and the free end of the bottom tag, the card board being sufliciently thick to so space the lower tag from the'table 80 as to prevent engagement of the feed block 115 therewith f and so positioned upon the tablelSO as to not interfere with the movement of the feed bar 112 or feed blocks 114 and 1 15.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that various changesin the shape, s ze and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.
